The present research conducted a parametric study on an embossed plate heat exchanger (plate FIX) type adsorption chiller with SWS-1L and water pair, using a numerical method. The plate FIX has a relatively high heat transfer capacity and compact size, and this study is a first attempt to apply the plate FIX as a new type of adsorption chiller, as an improved alterative to the fin-tube type heat exchanger. A feasibility study was conducted on the base model and the result is comparable to the value for existing fin-tube type adsorption chillers. Furthermore, a parameter study was conducted for seven important design parameters, embossing diameter ratio, embossing height, embossing pitch, bed thickness, plate thickness, heating temperature and heat transfer fluid velocity. The results provided guidelines for the optimal designs of plate HX type adsorption chiller. The optimal values of COP and SCP were 0.5118 and 662.8 W kg(-1), respectively.
